To all whom t 'may concern Be it known that I,`EDwAnn M. HEYL- MAN, a citizen ot the United States of America., and resident of Rock Island,

Rock Island county, Illinois, have invented a certain new and useful Improvement in Engine Gang-Flows, of which the following isa specification.

My invention relates to improvements in engine gang plows-that is, to a gang plow which is adapted to bc drawn by an engine attached to the front of the frame.

The ol'ljects4 of my invention are to improve the general construction of this form ot plow and to provide an improved mechanism for adjusting the plow body to varying depths of the Jfurrow. Heretotore, in plows of this construction in which the plow beam is pivoted at its 'forward end, di'tiiculty has been experienced inthat in adjusting the plow beam vertically, the plow body would not be maintained in the same angular position with respect to the ground, and, therefore, the suction of the plow wo-uld vary depending` upon the vertical adjustment ot the same. i I have provided means for adjusting the plow whereby the plow is always maintained in the same parallel relation with respect to the ground and thus the same suction of the kplow is obtained. I likewise provide means whereby this parallel movement of the plow body is maintained while the plow body is `moved `upward or downward by the uneveness of the ground. 'Ihus as the plow is drawn across the eld and the gage-wheel rides along the uneven surface of the ground, thus raising and lowering the plow, the heel and toe of the plow body are always raised and lowered to the same extent, and thus the same suctionv oil' the plow is maintained irrespective of the curvature or unevenness of the ground. I, furthermore, provide improved means for ylocking the plow in` raised position.

A further novel feature of my invention isthe means for adjusting the depth of the suction oil the plow body, which means comprises'an adjusting screw vfor eachplow body and means whereby when the raising lever isv released the plow body will tall back to the desired adjusted position.

rI`hese and other objects of my invention will be more readily understood by having reference to the accompanying drawings yin which I have illustrated one embodiment of my invention. Y

Throughout the drawings similar reference characters reifer to similar parts.

Figure 1 represents a side elevation of .a gang embodying the features of my invention. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of a single plow beam and plo-w body, together with the mechanism associated therewith for operating the same. Fig. a is a detail view. Fig. 5 is a view similar to Fig. 3, but showing the plow beam in its raised position. Fig. 6 is a sectional view'talen on line 6 6 of Fig. 5. Fig. 7 is a plan view of Fig. 3. Fig. S is a sectional view taken on line 8 8 of Fig. 8. Fig. 9 is a sectional view taken on line 9-9 of Fig. 8. Fig. 1() is a sectional view taken on line 10,-.-10 of Fig. 3. Fig. 11 is a sectional view talren on line 11-11 of Fig. 3. Fig. 12, is a sectional view taken on line 12-12 of Fig. 3. Fig. 13 is a sectional view taken on line 13-13 ofFig. 3.

In Figs. 1 and 2 I have illustrated diagrammatically the manner in which a plurality of plow beams are associated together in an engine `gang plow. As represented, there is provided a suitable frame 15, to which is secured the inclined rear bar 16 to which the various plow beams are secured. Mounted in this 'frame 15 are the land wheels 17. This frame can .be of any desired construction, and as the same comprises no part of my present invention, it is not ,thought necessary to show or describe the `same `more in detail. @t course, it is understood that in an engine gang the engine for driving the gangs is usually attached in front of this frame, but in order to avoid unnecessary complications in the` drawings, I have omitted all reference to the plow body 21a, is pivotally mounted hetween the rear ends of these members 18 and 19, being pivotally connected thereto by means of the bolt 22.

Secured to the casting 20 there is an upwardly extending bracket 23, to which the connecting rod 24 is pivotally connected. The rear end of this connecting4 rod 24 is threaded into the socket 25 which is pivotally connected to one arm 26 of a bell crank. This bell crank is pivotally mounted between the brackets 27 and 28 carried by the two members 18 and 19. The other arm 29 of the bell crank extends substantially at right angles to the arm 26, and pivotally connected to this arm 29 there is a link 30 which, at its opposite end, is connected to the forward end of the curved member 21.

A casting 31 is pivotally mounted on the blocks 31a mounted between the members 18 and 19 by means of the bolt 32, which casting carries the standard 33 of the gage-wheel 34. A balance spring 35 to assist in raising the plow is connected to the ear 36 secured to the casting 31, and the ear 37 mounted on the member 18. A pair of triangular-shaped brackets 38 and 39 are .mounted upon the members 18 and 19, and pivotally mounted in the upper end of these brackets is the raising lever 40. Extending' substantially at right angles to this raising lever and rigidly connected thereto, there is a arm 41 pivoted to a link 42, the lower end of which second link is connected to the casting 31. Pivoted to this casting 31 there is a curved arm 43 which is provided with a flat end portion 46 which is adapted to engagev the finger-shaped end of the arm 29 of the bell crank. The position of this arm 43 is adjusted by means of the screw bolt 44, the lower end of which bolt bears against the curved socket 45 provided on the casting 31.

I-Iaving now given a general description of the construction and arrangement of the various parts of the gang, I will describe the operation of these parts when the plow body is raised and lowered, and the manner in which these parts operate when the plow body is adjusted to cut furrows of various depths. Starting with the parts in the position shown in Fig. 3, in order to raise the plow body from the ground, it is merely necessary to press downwardly upon the raising lever 40, which operates through the vmedium of the arms 41 and 42 to press downwardly upon the casting 31 and thus upon the gage-wheel 34, and this operates to raise the plow beam, and plow body into the position shown in Fig. 5. It will be noticed that when the parts are in this position the arms 41 and 42 have been moved slightly past dead center, and in this manner the plow is locked in raised position. When it is desired to lower the plow, it isV merely necessary to pull up on the raising lever 40, which breaks this locking connection and permits the plow beam to move downward into the ground until the finger end of bell-crank arm 29l strikes the portion 46 of the curved arm 43. Further downward movement of the plow is prevented on account of the engagement between the finger portion 46 of the bell crank arm 29 and the arm 43. It will be noticed that in this downward movement of the plow body the same is always maintained in the same angular relation to the ground line. This is accomplished by means of the relation of the connections consisting of the members 18 and 19 and the rod 24.

If special provision was not provided, it

would be evident that when the plow beam was swung downward that the heel of the plow would move into the ground at a more rapid rate than the toe of the plow, and the angular relation of the plow body would, therefore, be changed and the suction ofthe plow therefore accordingly varied. This is obviated, however, in my construction, as when the plow bea-m' is swung downward the connecting rod 24 pulls forward upon the arm 26 of the bell crank, which thus causes the arm 29 of this bell crank to push downward upon the forward end of the curved member 21 which carries the plow body, .and in this manner maintains this plow body in the same angular relation to the ground line. It will further be noticed that the greater part of the weight and suction of the plow is removed from the connecting rod 24 and is carried vrby the gage 'wheel 34. This is accomplished by the fact that the entire weight and suction of the plowl body is carried by the members 18 and 19 and by the arm 29 of the bell crank which bears against the arm 43 carried by the casting 31, as the link 30 is pivoted about midway of the arm of the bell crank 26, and by this construction the downward suction is carried on the pivot of the bell crank 26 and the arm 43. This relieves a large amount of strain from the rod 24. This rod 24 is threaded at one end with a right hand thread and at the other end with a left hand thread, and by turning this rod in either direction the suction can be increased or decreased, as desired. With thisV arrangement, it will be noticed that as theV plow is drawn over the ground and the gage wheel rides in .and ont of the depressions, the plow body is likewise raised and lowered, but is Vall the time maintained in the same angular relationship through the ground, and thus al-v ways maintains the same degree of suction.

While I have shown and described one embodiment of my invention, it will be understood, ofcourse, that I do not wish to be limited to the exact construction shown and described.
